Acoustic absorption is usually defined in terms of an absorption coefficient(usually denoted by the Greek letter
alpha, α), defined as the ratio of absorbed to incident sound energy from a single interaction between a sound
wave and a certain material.
Absorption coefficients range from 0 to 1 and vary with frequency,
α=0 means that the material absorbs no sound and reflects all sound energy incident on it.
α=1 means that the material absorbs all sound energy incident on it and reflects none.
Absorption coefficients of 0 and 1 are ideal values that do not exist in reality because all materials reflect and absorb
In general, materials having absorption coefficients less than 0.15 are considered to be reflective and those having
absorption coefficients greater than 0.4 are considered to be absorptive.
As you can see our Testing report show that our products have a very good performance in a large range of
Typeset and adjust SWAN-LAKE polyester acoustic board to certain shape on the performed section.
Either mechanical or hand-cut; recommend rigid steel ruler if you decide to cut by hand and you’d better use
imported art blade.
We have special chamfering tool to chamfer various bevel edge so as to meet different aesthetic point of view.
We mainly use glue such as spray glue, hot melt adhesive, white glue, glass glue, etc. (according to different
surface) to stick acoustic panels onto the wall. For flat cement wall, you may install the boards directly with
white glue and gun nail, which is glue-saving and time-saving. Pasting sing-side glue on the based surface is
strongly suggested as well as layering process.
